West Ham boss Manuel Pellegrini signed nine new players in the summer, but it is clear to see that his work is far from finished at the London Stadium.
One particular area where the Hammers might be looking to improve is their right-back department, with Pablo Zabaleta set to turn 34 in January, Ryan Fredericks out with a long-term injury and Sam Byram (currently out on loan) still yet to convince in east London.
According to the Sun, one of Pellegrini's key summer targets is Manchester United ace Antonio Valencia, and if the Chilean manages to bring the 33-year-old to West Ham, he really could be a great addition for the club, if not a short term fix.
The Ecuadorian joined United from Wigan Athletic in the summer of 2009, for a fee believed to be worth somewhere in the region of £16 million, and he has gone on to make 336 appearances in all competitions.
Valencia originally operated as a right winger, but he has evolved into a right full-back, and he would bring real competition to Zabaleta and Fredericks at West Ham.
The Manchester United ace possesses pace in abundance, in spite of his advancing years, and he would offer Pellegrini a real attacking threat down the right hand flank from defence.
Valencia could also be used in a more attacking role for West Ham, and would add a certain kind of winning mentality to Pellegrini's side - something that they currently lack.
The 33-year-old would obviously only be a short-term fix, however.
Considering his undeniable quality, though, West Ham would be foolish not to pursue a move for the Man United skipper.
The fact that he will be available on a free transfer in the summer makes a potential deal for Valencia all the more appealing for the Hammers.
